Strange Looking Topography...

That's what I thought when I first noticed this:

Without my distance glasses, I'd say they looked like dirty sand dunes or something like that.  But Shiloh isn't in the sand.  I took these pictures at the Shiloh Junction when waiting for a ride.

Considering what else is in the pictures, it's pretty easy to guess.  Those are special covers to protect fruit trees from "predators."
